IMPBOVEMENT IN GOFFEE-POTS.

SPECIFIATION- TO ALL PERSONS TO *WHOM THESE PRESENTS SHALL OOME:

Be it known that I, JMS H. LEE, of Charlestuwn, in the eounty of Middlesex, and State of Massachusetts, have invented an Improve'd Cafetire, 01'. apparatus for making decoctions o'r infusions of cofi'ee or other thatters; and I do hereby declare the some to be fully described in the following specification, and represented in the accompunying drewing, whichdenotes a vertical section of it.

In such dr'awing, A den otes a. boiler or close vcssel, provided with a. neck, or volve-Seat b, to support a.

fiexile valve oi' washer,.a, festend to a staple, e. The said volve-Seat has one or more openings, cl, leadinga through itinto the i'lessel A. The volve-sent s eoncentric with o tube B, which has openings 'e e, leadingout of it neor its lower end, and extende down into the' boiler A to its bottom. The tube B projects above the top of the boiler a. short distonce, and has a. mole screw, f, cut on it for the purpose of securing upon it a; coffee-pot D, which at bottom is provded with a female screw soeket g, to screw upon the tube B, aiid so that the bottom i of the pot D meybe mode to fit closely down upon the washer 01' volve a, and cause it to close the openings d d.

The scx ews also a'llow of the'detachmentof the c'ofi'e-pot and boiler, as occasion mey'require. Extending up from 'theseid-prtg, and Opening into the tube B, is a tube H, which is arranged concentrically withinthe pot D, :mis surmounted by nother tube E, which encompusses and fits upon it, as shown at h. The tube E is i isfoi'aminous in its sides,'a.nd extends up through a cofi'ee-holder, or vessel, F, which is supported* 1 closed at top, in position by being ct' 'its bottom fix'edcto the tube A 'Safety-hell cep G, extends above and about the cofl'eeholde F, und is fitte to it by a. tapering joint, as seen uti 2'. Another such bell-cover G encoinpasses the Safety-hell cap G, rises up from th'e mouth of the pot D, and' "should be fitted to such mouthiby means of o. lock-joint, or by being screwd into it; There should be a space k between the eover G and the cap or cover 0,: 1

and theremay'be a, Small hole h' in the top of the cover G, or its hole may be covered with wire gauze, the hele being for the' escape of steum from the cese G. A Spring m, otteched to the top of thecover C, resses the cep 3 Gdown upon its Seat i. 'The pot D has a. spout n, provided with a. close-fitting cover or cap, 0. There is :1.150 a handle 10 to the pot D,'a,nd another handle q to the boiler A, the some beingermnged as represented. In using the coffee-preparing apparatugthe ground cofi'ee is to be placed in the receiver F, and the water iu the boiler-A; While the water may be in'a boiling state, it will genefate steam, which, ressing on.the water, will force it into and through the pipe B, and thence through the pipes H and E, and into and upon the coifee iu the receptaole i e through which it will percolate end fall into the cofee-pot D. The Safety-cap Gwill allow the cofi'ee to swell, and will rise under the pressure of the cofi'ee, should it swell so much os to overeome the pressure :it the snring m. For convenience and economy, it is advontageous to have the coffee holder F in connection with the eofi'ee pot, after the latter may have l be efi'ected by my preseut cofetire. The Coffee-making uppcratus rcently petented by me, does not admit of such, on account of the tubo which proceeds down from the cofi'ee-holder going below the coifee-pot. i In present apparatus I do not apply one S1 nstead the'reof, make use of three separate tubos, B, H, and E, that is, one to each of the vessels A, D, and F,

the top or month of the cofi'ee-put. 'This enables me not i i only to detach the cofi'ee-holder from the cofl'ee-pot, but the letter from the boiler, as occasion may require. As u the boiler has to ,be supplied with-water through the tube B, I employ the Opening d, and thecap or washer hai; air may escape from the boiler during the process of filling it with water, such u the tube H being exten'ded neerly if not ,quite up to volve a, end seet'b, in order t volve being subsequently elos down upon the volve.

I claim as my invention, 'pot D, and the vessel F.

I also claim'the com the vessel F. i

I also claim the combination the pipes H, E, B, or their equivalents, the cofi'ee-pot D, and the boiler A.

I also cleim the combination and ormngement of the Seat b, one or, more-openi washer a, and the screws f, g,-with Opening into it us specified.
